Q:

The capacitor doesn’t allow sudden changes in ___________

A) Voltage B) Current
C) Resistance D) Capacitance
 
Answer & Explanation Answer: A) Voltage

Explanation: Any small change in voltage occurs within zero time across the gives an infinite current which is practically impossible. So, in a fixed capacitor, the voltage cannot change abruptly.
